IStat Troponin I AMR Validation

I have a facility in my region that is trying to validate the lower range AMR for IStat troponin. The linearity material given by abbott only goes down to 0.42 ng/mL and the lower end of our linear range goes down to 0.00 ng/mL. Does anyone use a 3rd party kit to validate lower ranges? Is so what do you use and what lot are you currently using?

Samples from healthy donors can be used. Refer to pg. 4 of the cTnI performance verification protocol.

We have diluted the level 1 control with negative patient plasma, usually 1:4 to get down closer to 0.   We've also used negative patients too.
